SDC 451V – Frequently Asked Questions

1) What is the difference between the SDC 451 and 453P push button switches?
Both are SDC 450 Series vandal resistant push buttons, and the difference is what happens after you press. The 451 is alternate action (AA) on/off: press once to release, press again to restore, so the door stays unlocked until someone presses again. The 453P adds a pneumatic timer adjustable from 1 to 45 seconds, so the lock re-secures on its own after the delay you set. Use the 453P where you want an entry or exit release that cannot be left unlocked by accident. Use the 451 where staff need to hold a door in an unlocked state, for a delivery window or a shift.
2) Will the SDC 450 Series push button fit a standard single gang box?
Yes. The 450 Series is offered in a single gang size that mounts to a standard single gang electrical box, and in a narrow size for mullions and other tight mounting locations where a single gang plate will not sit flat. Both the 451 and the 453P are available in either size, so you pick the operation first and the plate size second.
3) Is there a push button switch that holds up to abuse in a school or detention corridor?
That is what the SDC 450 Series is built for. The faceplate is 1/4 inch thick aluminum and the button is all stainless steel, an assembly rated by SDC to take hammer blow impacts. Mounting screws are security spanner type and are then hidden under tamper resistant aluminum plugs, so there is no exposed fastener to back out. It is a commercial-duty device, and SDC lists correctional and detention centers, schools, and high-security government facilities among its applications.
4) Should I use a flat vandal resistant push button or a mushroom style exit button?
Two different jobs. The SDC 450 Series is a flush stainless steel button behind a 1/4 inch aluminum plate, meant to resist deliberate abuse and to be hard to hit accidentally, which is why it suits corridors and public-facing walls. A mushroom button stands proud so it can be struck fast and found by feel, which is what you want on an emergency release. If that is the requirement, ZenSupply carries the Dortronics 5210 Exit Release with a 1-9/16 inch red mushroom button marked Push to Exit / Emergency Release on a single gang plate, and the Camden CM-5000 Series 2-3/8 inch mushroom pushbutton on an aluminum faceplate.
5) The opening has a narrow aluminum stile. What are the options if a single gang plate will not fit?
The SDC 450 Series is built in both a narrow and a single gang size, in both the 451 alternate action and the 453P pneumatic timer models, so a narrow stile takes the same switch and the same tamper resistant construction as a single gang wall box. The Dortronics 5211-MP23 mushroom exit release is mounted on a single gang plate, and the Camden CM-AF500 indicator is likewise a single gang device, so those go on the wall rather than the stile.
6) What tool do I need to install or service an SDC 450 Series push button?
A spanner bit. The 450 Series mounts with security spanner screws, and those screws sit under tamper resistant aluminum plugs that have to come out first. Plan on carrying the spanner driver to the job, because a standard Phillips or Torx will not touch it, and budget for the plugs if you expect to open the plate again later.
7) How do I set the re-lock delay on an SDC 453P?
The 453P uses a pneumatic timer, adjustable anywhere from 1 to 45 seconds. It is a mechanical air timer built into the switch, not a programmed electronic board, so you set the delay at the device itself and it holds that setting without power or configuration. Short settings suit a single person passing through; longer settings suit carts, gurneys, or deliveries.
8) Can I use an SDC 450 Series push button as a restroom occupied indicator?
No. The 450 Series is a switch, not an indicator; it has a stainless steel button and no lamp or legend. For an occupied indication you want a separate annunciator, such as the Camden CX-WC Series CM-AF500 single gang LED Occupied When Lit indicator. The two are commonly installed together, the switch inside the room and the indicator outside it.
9) Can I use the Camden CM-AF500 in place of an SDC 450 Series switch?
No. The Camden CM-AF500 is a single gang LED Occupied When Lit indicator, so it reports a status to the person outside the room rather than switching anything. The SDC 450 Series is a push button switch, in 451 alternate action on/off and 453P pneumatic timer models. The two are often installed together on a restroom or exam room opening, the SDC button switching the lock and the CM-AF500 showing occupancy, but the indicator will not release a door on its own.
10) Are the SDC 451N and 453PN different products from the 451 and 453P?
They are the narrow-plate versions of the same two switches. The 450 Series covers models 451, 453P, 451N and 453PN, which is the 451 alternate action and the 453P pneumatic timer each in narrow or single gang. Order by the model plus the size, and you have named the part.
